Background technology
Along with the continuous development of computer network and automatic control technology and the deep application in electric power system, the automaticity of electric power system is also more and more higher, reliable guarantee is provided for the safe and stable operation of electric power system, be the intensive management of transformer station simultaneously, realize that few people, unattendedization provide technical guarantee.Building Surveillance center is that electric power system realizes few people, unwatched inevitable outcome,, Surveillance center unattended in transformer station concentrates under the operational mode that monitors control, just necessarily require centralized control system can reflect the ruuning situation of each controlled unattended substation in real time, accurately and efficiently, highly reliable real-time data acquisition treatment system just must be arranged and realize this goal.
The data acquisition of Surveillance center is that Surveillance center realizes basis that each controlled transformer station is controlled in real time in the distance, data acquisition can liken Surveillance center's eyes and ear to, collect the needed real time data of collection control operation by eyes and ear, have only these data can accurately, in time, intactly be transferred to Surveillance center, could in time send accurately controlled transformer station, control action and instruction reliably.Because equipment link and network link on the data acquisition channel are more, from the telemechanical apparatus of substation and the communication equipment of substation, to electric power system transmission medium (as OPGW, ADSS etc.), arrive the communication equipment of main website again, the last front server that could arrive main website, data acquisition is through so many links, and the obstacle of any one link or fault all can cause data acquisition to occur wrong or interrupt.Existing data acquisition system mainly adopts active and standby pattern, the telemechanical apparatus that is the front server of main website and substation is all with active and standby mode operation, when main frame breaks down when active and standby switching or manual active and standby switching, because life period interval (about 20 seconds) between transfer period, standby host this moment normal transceive data still, often cause loss of data in short-term, even when the standby host fault, main frame switches to standby host and causes active and standby handoff failure, can cause when long transfer of data to interrupt, as in certain telemechanical apparatus fault of transformer station, certain front server fault of Surveillance center, and all can cause loss of data and uncontrollable problem during cross faults, reduced the reliability and stability of Surveillance center.
Summary of the invention
Be to overcome the deficiencies in the prior art order of the present invention, a kind of power real-time data acquisition system based on multi-machine balanced while line model is proposed, native system constitutes two local area network (LAN)s with transformer station's telemechanical apparatus of the front server of online no active and standby branch of maximum six whiles and simultaneously online no active and standby branch by data dispatching private network and private line network, solved certain telemechanical apparatus fault in transformer station, certain front server fault of Surveillance center, and loss of data and uncontrollable problem during cross faults, strengthened the reliability and stability of data acquisition processing system.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of power real-time data acquisition system based on multi-machine balanced while line model, comprise at least two front servers and two transformer station's telemechanical apparatus, front server and two transformer station's telemechanical apparatus link together by the data dispatching private network, the front server that is connected with the data dispatching private network is connected on two monitoring major networks simultaneously, two monitoring major networks also are connected on other two front servers simultaneously, and these two front servers are connected with two transformer station's telemechanical apparatus by private line network.
And, described two front servers by the annexation of private line network and two transformer station's telemechanical apparatus are: it is online that two front servers all are connected to two data acquisitions simultaneously, two transformer station's telemechanical apparatus are connected respectively on the input of channel switching device, and it is online that the output of this channel switching device is connected to two data acquisitions through special line by MODEM.
And described two front servers that are connected with the data dispatching private network all adopt the form of network card binding to be connected with the data dispatching private network.
And the quantity of the described front server that is connected with the data dispatching private network is 2～4.
Advantage of the present invention and good effect are:
1. the notebook data acquisition processing system adopts data dispatching private network and private line network to carry out transfer of data, every kind of transmission network is connected with respectively and simultaneously onlinely is regardless of active and standby front server and simultaneously onlinely is regardless of active and standby transformer station's telemechanical apparatus and constitutes two local area network (LAN)s, improved the redundancy of data acquisition system, can realize zero second seamless switching, any front end processor or any one transmission channel break down in the data acquisition processing system, single-point appears, even two point, multiple spot, can not influence the data acquisition and processing (DAP) of whole data collection treatment system, can not lose any data, the only surplus front server of system, also can handle the data of all passages, thereby solved certain telemechanical apparatus fault effectively in transformer station, certain front server fault of Surveillance center, and loss of data and uncontrollable problem during cross faults, strengthened the reliability and stability of data acquisition processing system.
The use of notebook data acquisition processing system initiative maximum 4 front servers of access dispatching data private network, utilize the communication mode of bus form, it is simultaneously online to pass through multimachine (maximum four front servers), equally loaded, the different channel allocations of same transformer station are in different front servers.
3. the notebook data acquisition processing system has made full use of existing data dispatching private network of grid company and private line network resource, has improved the utilance of power network resources effectively, has saved the investment of system.And the multiple communication modes of different principle comprises serial special line, network, adopts different front-end systems to carry out communication, carries out seamless switching in the centralized control system but can be unified in, and guarantees in the handoff procedure not obliterated data.
4. the present invention is reasonable in design, it forms two LAN system by data dispatching private network and private line network with four front servers and two telemechanical apparatus, solve loss of data and uncontrollable problem when certain telemechanical apparatus fault of transformer station, certain front server fault of Surveillance center and cross faults effectively, strengthened the reliability and stability of data acquisition processing system.
